A 15-year-old boy is expected to be charged with felony second-degree assault after he reportedly brandished a small pocketknife Wednesday at Albert Lea High School.

The teenager, whose name has not been released, allegedly flashed the knife at a 17-year-old boy in the commons, said Albert Lea Police Department Lt. J.D. Carlson.

Carlson said the incident took place at about 7:30 a.m.

The 17-year-old reportedly had been making squeaking noises with his shoes prior to the other student allegedly pulled out the knife.

Albert Lea Police Department school resource officer Ted Herman, who typically arrives at the school at about that time in the morning, investigated the situation after it was reported by the older teenager.

Carlson said the 15-year-old boy was not arrested, and he did not know whether the teen was suspended.

Herman is still completing his investigation. The charges would come in Freeborn County Juvenile Court.

If a juvenile is 16 years or older, proceedings and the name would be public.

Carlson said in addition to second-degree assault, the boy may be charged with having a knife on school grounds.

Albert Lea High School is at 2000 Tiger Lane.
